Hi,
managed to find all of this, was hidden away and had no lever!
got the pressure up, bled the radiators, the pressure dropped again so
topped it up to 1.0 bar.
now the boiler turns on, then goes off after approximately 30 seconds.
can't think why, any ideas?

there is a red plastic cap on top of the gauge, with arrows pointing in an

I found that turning it slowly, and holding it works, bu the pressure
drops
when doing this.... not goes up like i was expecting. i must be doing
something wrong?
That is the pressure relief valve. It's designed to open
automatically if the system pressure should go too high. Turning it
is a test function which releases some water and so the pressure will
drop. Just for reference.... Doing so is not a good idea because
you can get bits of crud from the system stuck in it and provoke a
small and steady seepage which is difficult to fix.
You need to look further. POssibly there or somewhere within
reasonable distance (a few 10s of cm) of a cold mains water supply,
there should be a threaded fitting about 25mm across. Nearby, there
should be a similar one on the cold mains supply. They look rather
like washing machine valves typically. There should be a braided
hose to connect the two, although that is supposed to be removed after
use so may have been lost.
the only braided hose i can see nearby is for the sink, i dont think there
is a lever nearby either...
Have a look on www.bes.ltd.uk
Then search using 11354 as a prodcut search (not part code)
http://www.bes.ltd.uk/products/109.asp
You are looking for some kind of arrangement like that or perhaps
something like 8148, 8165 or 15583 (further down the page)
The hose may have gone missing, in which case you'll have to buy one.
Plumbers merchants or B&Q Warehouse have them.
